好的,了解了您的需求,下面是一个简单的用Python实现的云笔记应用系统,其中使用了xlwings库实现Python与Excel的连接:
```
import xlwings as xw
class Note:
def __init__(self, title, content):
self.title = title
self.content = content
class NoteDB:
def __init__(self, workbook_path):
self.workbook_path = workbook_path
self.workbook = xw.Book(workbook_path)
self.sheet = self.workbook.sheets['Notes']
def add_note(self, note):
row = self.sheet.range('A1').end('down').row + 1
self.sheet.range(f'A{row}').value = note.title
self.sheet.range(f'B{row}').value = note.content
def get_all_notes(self):
notes = []
titles = self.sheet.range('A2').expand('down').value
contents = self.sheet.range('B2').expand('down').value
for title, content in zip(titles, contents):
if title is not None and content is not None:
note = Note(title, content)
notes.append(note)
return notes
if __name__ == '__main__':
db = NoteDB('notes.xlsx')
while True:
print('1. 添加笔记')
print('2. 查看所有笔记')
print('3. 退出')
choice = input('请选择操作:')
if choice == '1':
title = input('请输入笔记标题:')
content = input('请输入笔记内容:')
note = Note(title, content)
db.add_note(note)
print('笔记添加成功!')
elif choice == '2':
notes = db.get_all_notes()
for note in notes:
print(f'{note.title}: {note.content}')
elif choice == '3':
break
else:
print('无效的选择,请重新输入。')
db.workbook.save()
db.workbook.close()
```
这个代码实现了一个简单的云笔记应用系统,使用了xlwings库实现Python与Excel的连接,提供了添加笔记和查看所有笔记的功能。您可以根据自己的需求对其进行修改和扩展。注意:需要先安装xlwings库并且需要使用Excel 2010或更高版本。
